AI Technical Summary
Technical Problem
Existing direct reduction methods for producing steel emit significant CO2 and require adaptation to increase hydrogen content in the reducing gas without impacting productivity.
Method used
A direct reduction plant with a reformer comprising tubes for supplying either hydrogen or methane-containing gas, allowing flexible operation with variable hydrogen content, using green hydrogen and controlled heating to produce a reducing gas with high hydrogen volume.
Benefits of technology
Enables efficient production of direct reduced iron with reduced CO2 emissions and minimal equipment adaptation, accommodating variable hydrogen availability without productivity loss.
